On Label/Div or some other component, how to use setMarkupId and dynamic id

[Brown, Berlin [GCG-PFS]]

Is there a way to prefix a component with using setMarkupid but also
have the dynamic id.
 
I want my end output to have:
 
With Code:
 
x = new WebMarkupContainer("myId")
x.setMarkupId("myId");
 
<div id="myId_id2323" />
